Pois é, mais uma criação do Rainer (lembram-se dele?) https://www.audioanalogicodeportugal.net/t2521-a-obra-de-uma-vida?highlight=rainer
Depois de ter lançado mais um gira discos de grande qualidade a todos os níveis, lança agora no mercado um motor com fonte e sua gestão. Uma coisa do mais alto calibre e que um constructor alemão de gira discos vai passar a usar em exclusivo no seus gira discos.
Como sempre, o preço a pagar é o inconveniente quando se leva a mecânica e a electrónica ao limite.
The new dedicated intelligent drive unit Dereneville DAE-01 made in Germany.
The Dereneville DAE-01 by AVDesignHaus offers a unique perspective and user flexibility in
turntable motor units. All operational parameters can be set by manually using the push buttons
on top of the drive unit.
Additionally for convenience, the parameters can also be programmed via computer,
with the aid of our specially developed software.
The housing of this drive unit, made from high grade Aluminium, is specially designed
for the Papst-Synchronous motor VDC-3-43.10 937 4310 602 which allows for a vibration free
and low noise operation, thanks to the flexible mounting of the motor itself inside the housing.
The complete electronic control unit is safe and EMV tested and is integrated in the housing.
The integrated display shows every status and each step during programming by the buttons
on top. The brightness value is user adjustable as is the delay time for illumination decay.
This new developed drive unit offers three speeds: 33,33 rpm / 45,00 rpm / 78,00 rpm
and one hidden speed: 16,66 rpm and a pitch control over a very wide range whilst the
turntable is running.
This hidden speed of 16,66 rpm offers two advantages: firstly, you can play the old records
cut by 16,66; secondly, it lowers the platter to half speed in order to change the record more
safely whilst running. By pushing the 33,33 knob once, the speed goes down to 16,66 - and by
pushing it again, it will speed up to 33,33 rpm.
All speeds can be calibrated with exacting precision in very small steps 1,0 / 0,1 / 0,01 or
0,001 Once the speeds are calibrated, they can be stored in the memory of the electronic
board. This is possible for every set.
Usually you only have to adjust the main speed 33,33 rpm. The electronic control unit inside
calculates all other speeds exactly. Of course you can check them and calibrate them
The main memory is fragmented in three segments, called: set 1 / set 2 / set 3. This means,
that you can illustrate three different, virtual drive units in just one.
For example, if you have up to three turntables, then you can use only this one drive unit to
play them perfectly, each at a time. Just place the drive unit to that turntable you want to play
and recall the set for this turntable. The hours of operating of the three sets will be counted
separately, together with the total hours of drive play.
Each Set has its own operation hour control and supports the belt and up to three needles.
In practice: if you have two or three tone arms mounted at your turntable, all with different
cartridges, you can assign them to (nd: needle) nd 1, nd 2 and nd 3. This means, that you can
monitor operational duration of a single or multiple cartridges, every time you want. This is a
useful application to determine stylus degradation over time.
You can, for example, program a user-defined time period for oiling the bearing of the
turntable. This drive unit will store this and implement it for you. And you will get the exact
time to change the belt or string in the preselected time.
Different turntables have different platter weights. Our drive unit offers the best possible
approach to generate the perfect time for accelerating and decelerating. This preserves the
belt or the string from damage. All values can be programmed separately in each set and they
can be stored in the main memory of the electronic unit and also on your computer.
This unique feature, along with the other applications, are suitable to programming via
computer. The connection has to be made via USB-II cable.
Connectors for rev meter and USB-II
Our -motion animation- means you can program any number of individual times from 1 hour
up to 7 days to run the turntable, for example 1 minute or more, at a lower speed. This
ensures that the oil in the platter bearing will be evenly shared and the belt or string will find
another position, preventing damage to the turntable and belt.
This drive unit has an input for an external pulse signal from the platter. You can create
several markings underneath or at the outer face of the platter and strobe them. The
electronic control unit can interpret this signal and will regulate the target value.
This feature is only for people, who are well schooled in electronic circuits.
This drive unit works only with 20 to 24 VDC. A special Power supply is included in delivery.
The complete electronic control unit is integrated on board the drive unit. All diagnoses and
updates can be done via internet.
This high end drive unit is manufactured and assembled in Germany and conforms to
RoHs standards and correlates with the European CE and the FCC in the United States.
The Dereneville DAE-01 will only be produced in limited batches.
